Kaspa vs Solana
How Kaspa and Solana differ on speed, security model, supply and mining.
Solana and Kaspa are both built for speed, but they get there differently. Solana uses proof of stake and a schedule of rotating leaders who each produce blocks in turn. Kaspa is proof of work with no leaders at all: any miner can produce a block, and parallel blocks are merged in a blockDAG.
In the time Solana produces one block, Kaspa produces about 4.
Kaspa vs Solana: side by side
| Kaspa (KAS) | Solana (SOL) | |
|---|---|---|
| Launched | November 2021 | March 2020 |
| Consensus | Proof of work (GHOSTDAG blockDAG) | Proof of stake with Proof of History |
| Mining algorithm | kHeavyHash | None (validators stake SOL) |
| Block time | 0.1 s (10 blocks per second) | About 0.4 s slots |
| Structure | BlockDAG: parallel blocks are all kept | Single chain with a rotating leader schedule |
| Supply | Capped at about 28.7 billion KAS | No hard cap; inflation declining toward a long-term floor |
| Issuance | Smooth: reward drops about 5.6% every month, halving yearly | Staking inflation |
| Launch | Fair launch, no premine or pre-sale | Token sales to investors before launch |
| Hardware | kHeavyHash ASICs | High-spec validator servers |
The short version
- Solana offers very high throughput and a large app ecosystem, secured by staked SOL.
- Kaspa matches sub-second block times with proof of work and no leader schedule to target or censor.
- Kaspa had a fair launch; Solana's tokens were partly sold to investors before launch.
Frequently asked questions
Is Kaspa faster than Solana?
They are in the same range. Kaspa targets a block every 0.1 seconds; Solana's slots are about 0.4 seconds. Solana currently handles more transactions per second in practice.
Does Kaspa have validators like Solana?
No. Kaspa has miners, not validators. There is no staking, no leader schedule and no validator set.
Which is more decentralised?
It depends on the measure. Kaspa's proof of work lets anyone mine without permission or stake. Solana's validators need significant stake and powerful hardware.
